My local performance brake shop (very reputable place) told me to hold off a year on the composite pads, as he has seen some cracking/fragmenting occur on the street versions. He feels that the wrinkles are still being worked out, on the composites and on the new ceramics as well. Have you heard anything about these problems, or is he being conservative. (he does lots of Ferraris, Vettes, Cobras, Lotus, etc.)
